  • Just to add another voice to the post. I just installed the beta. It DID take, but, it totally stalled on the Restating Watch screen. I waited a good (7) minutes, and it was just stuck on that screen, and no button pushes "nudged" it to turn over. I had to do a hard reset to get the watch to work like it usually would.

    This is the first time this happened, but not the first time something has gotten stuck graphically. The Loading Maps screen also got locked after unplugging the watch from my PC and syncing it to Garmin Express. That hasn't happened recently, but it's another example of something getting stuck.
